基于elementUI实现一个可编辑的表格（简洁版）

需求：

实现一个可编辑、增加、删除的表格，每一项是可编辑的输入框、

注：使用vue3+elementui

实现

1、dom部分

<el-form :model="formData" ref="formRef"><el-table :data="filteredTableData" border fit max-height="800"><el-table-column label="序号" width="100" align="center"><template #default="{ $index }">{{ $index + 1 }}</template></el-table-column><el-table-column label="手机号" align="center"><template #default="{ row, $index }"><el-form-item:prop="`tableData.${$index}.phone_num`":rules="phoneRules"><el-input v-model="row.phone_num" placeholder="请输入手机号" /></el-form-item></template></el-table-column><el-table-column label="年龄" align="center"><template #default="{ row, $index }"><el-form-item:prop="`tableData.${$index}.car_plate_num`":rules="plateRules"><el-input v-model="row.car_plate_num" placeholder="请输入年龄" /></el-form-item></template></el-table-column><el-table-column label="身高" align="center"><template #default="{ row, $index }"><el-form-item:prop="`tableData.${$index}.vin`":rules="vinRules"><el-input v-model="row.vin" placeholder="请输入身高" /></el-form-item></template></el-table-column><!-- 操作列 --><el-table-column label="操作" align="center" width="100"><template #default="{ row, $index }"><el-icon color="#f56c6c" @click="deleteFilteredRow($index)"><Delete /></el-icon></template></el-table-column></el-table><el-button style="margin-top:10px" type="primary" plain @click="addRow">+ 添加</el-button></el-form>

2、js部分

// 搜索相关变量
const searchPhone = ref('')
const filteredTableData = ref([])
const originalTableData = ref([])
const tableData = ref<ChargeConfig[]>([]);
// 表单数据
const formData = reactive({tableData: [{ phone_num: '', car_plate_num: '', vin: '' },],
})
const formRef = ref<FormInstance>()
// 表单校验部分
const phoneRules = [{ required: true, message: '请输入手机号', trigger: 'blur' }, { pattern: /^1[3-9]\d{9}$/, message: '请输入11位手机号', trigger: 'blur' }]
const plateRules = [{ required: true, message: '请输入年龄', trigger: 'blur' }]
const vinRules = [{ required: true, message: '请输入身高', trigger: 'blur' }]// 表单数据
const formData = reactive({tableData: [{ phone_num: '', car_plate_num: '', vin: '' },],
})
const formRef = ref<FormInstance>()
const whiteListVisible = ref(false)// 手机号搜索方法
const handlePhoneSearch = () => {const keyword = searchPhone.value.trim()if (!keyword) {filteredTableData.value = [...formData.tableData]} else {filteredTableData.value = formData.tableData.filter(item => item.phone_num && item.phone_num.includes(keyword))}
}
// 重置搜索
const resetPhoneSearch = () => {searchPhone.value = ''filteredTableData.value = [...formData.tableData]
}
// 删除行
const deleteFilteredRow = (index: number) => {const deletedItem = filteredTableData.value[index]// 从原始数据中删除const originalIndex = formData.tableData.findIndex(item => item.phone_num === deletedItem.phone_num && item.car_plate_num === deletedItem.car_plate_num && item.vin === deletedItem.vin)if (originalIndex > -1) {formData.tableData.splice(originalIndex, 1)}// 更新过滤后的数据handlePhoneSearch()
}
// 添加行
const addRow = () => {resetPhoneSearch()const newRow = { phone_num: '', car_plate_num: '', vin: '' }formData.tableData.push(newRow)handlePhoneSearch()
}
// 保存
const saveList = () => {// 校验一下表单填写formRef.value.validate(valid => {if (!valid){ElMessage.error("请填写表");return;}// 校验成功，调用接口保存操作}).catch(() => {ElMessage.error("校验失败，请刷新重试");})
}

3.css部分

这里主要是调整一下表格内输入框的位置（看你自己需要，可不用）

<style scoped>
:deep(.el-table .cell) {padding-top: 12px!important;
}
</style>

end~
